Incorrect computation of shrink-to-fit width for block with white-space:nowrap and floating children

Per http://www.w3.org/TR/CSS21/visudet.html#Computing_widths_and_margins when width is auto then floating non-replaced,
absolute non-replaced, and inline-block non-replaced elements should use shrink-to-fit width. This trumps any no-wrap property
on the element so if we are shrinking to fit ensure our minimum width respects all possible line breaks.
